Description

  The present invention relates to a packaging container that is detachable from a can filled with soft drinks and the like and is suitable for packaging foods and the like.

  2. Description of the Related Art Conventionally, at a tourist spot or in a long-distance train, a can-type container filled with soft drinks and the like is used as a so-called “bonus” as food such as confectionery and small toys for children (hereinafter referred to as “confectionery”). ) Are sold. In these commodities, the packaged confectionery is usually mounted not on the cylindrical peripheral portion of the can-shaped container but on the cylindrical upper bottom of the can-shaped container for convenience of storage and transportation of the commodities. As for the method of mounting the packaged confectionery in a can-shaped container, in order to prevent the confectionery from being damaged or falling off, the confectionery is loaded into a cylindrical container molded of plastic or the like, and the confectionery is placed in a can-shaped container. A method in which a container and a can-shaped container are brought into contact with each other by fitting a shrink tape onto the cylindrical upper bottom of the container. In addition to the shrink tape, there is also a method in which a heat-shrinkable sheet is wound and heated to bring the container and the can-shaped container into contact.

  However, in the above-described conventional technique, the method of winding the shrink tape around the container and the can-shaped container requires time and effort in production, and when the tape is peeled off, the adhesive remains in the can-shaped container, and the hand is left untouched. There is a problem that there is a feeling of stickiness. Further, once the tape is peeled off, it is not possible to pack the remaining confectionery and the like again in a container and mount it in a can-shaped container. Furthermore, the peeled tape must be discarded as garbage, which is not preferable from the viewpoint of ecology, which is a social trend.

  Also, if a can-type container cooled in a refrigerator or the like is left in the air at room temperature, dew condensation may occur on the surface of the can-type container, but the above method does not necessarily ensure waterproofness. However, there is a problem that water due to dew condensation may enter the container and wet confectionery and the like.

  On the other hand, the method of bonding the container and the can-shaped container with the heat-shrinkable sheet requires passing through a certain production process, so that the container and the can-shaped container cannot be easily bonded at a store or the like, There is a problem that it takes time and cost. Further, it has the same problem as the case where the shrink tape is used.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a packaging container that is detachable from a can-type container and is suitable for storing and protecting articles.

  The present invention has taken the following measures in order to achieve the above object.

  The present invention is a packaging container fitted to an upper portion of a can-shaped container, wherein a bottom portion, a peripheral portion formed to be continuous with the bottom portion, and a continuous portion formed to be connected to the peripheral portion, the upper end of the can-shaped container And a side portion including a fitting portion fitted to the portion. The side portion has a configuration in which the maximum diameter is smaller than the maximum diameter of the can-shaped container.

  With such a configuration, the packaging container can be fitted to the can-shaped container, so that the packaging container can be detachably attached to the can-shaped container with one touch. Further, even in the case where the packaging container is packed in a can-type container and transported, the packaging containers can be prevented from coming into contact with each other due to vibration and coming off. In addition, even if the packaging container is attached to the can-shaped container and the can-shaped container is turned over, the packaging container does not directly contact the ground, so that the packaging container comes off and the contents are released. Nothing.

  As described above, according to the present invention, it is possible to obtain a packaging container that is detachable from a can-shaped container and is suitable for storing and protecting articles.

(Embodiment 1)
Next, Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view when the packaging container according to Embodiment 1 of the present invention is mounted on a can-type container. FIG. 2 is an overall perspective view of the packaging container according to Embodiment 1 of the present invention. In the following description, as illustrated in FIG. 1, the can-shaped container is assumed to be a container having a narrowed end used in a normal beer can or the like. That is, the can-shaped container 2 is a can-shaped container having a smaller diameter at the end portion than at the cylindrical peripheral portion.

  The packaging container 1 according to the first embodiment of the present invention has a truncated conical shape with an open bottom, and this opening fits into the cylindrical upper bottom of the can-shaped container 2. The upper bottom portion 3 of the packaging container 1 has a flat surface for attaching an advertisement label or the like. Further, the diameter of the upper base is configured to be slightly smaller than the diameter of the lower base. This is because the packaging container 1 is integrally molded with a mold (not shown) and then the packaging container is easily removed from the mold.

  Further, as shown in FIG. 1, the maximum diameter of the packaging container 1 is formed so as to be smaller than the maximum diameter of the can-shaped container 1. Accordingly, even when the packaging container 1 is packed in a box with the packaging container 1 mounted on the can-shaped container 2 and transported, it is possible to prevent the packaging containers 1 from coming into contact with each other due to vibration. Further, even if the container 2 is turned over while the container 1 is mounted on the container 2, the container 1 does not come into direct contact with the ground. No objects are released.

  A first rib 5 for increasing the rigidity in the vicinity of the upper bottom 3 is provided around the periphery 4 of the packaging container 1. The presence of the first ribs 5 prevents the corners where the upper base 3 and the peripheral part 4 intersect from each other even if a force is applied to the packaging container 1 in an oblique direction to the upper base 3. can do. It is considered that the greater the number of the first ribs 5, the higher the rigidity can be. However, for convenience in construction, five first ribs 5 are provided in the first embodiment. However, it is not limited to this.

  Further, a second rib 6 is provided around the peripheral portion 4 to increase the rigidity of the entire container against a force applied to the packaging container 1 in the vertical direction. As will be described later, the packaging container 1 according to the present invention is detachable from the can-shaped container 2 and is usually manually attached to the can-shaped container 2. It is necessary to push the packaging container from above with a certain amount of force in order to fit them together. The presence of the second rib 6 prevents the packaging container 1 from being easily deformed even if the packaging container 1 is fitted into the can-shaped container 2 with force. In the first embodiment, the second rib 6 has a triangular cross-section and is protruded in the direction of the maximum inclination angle of the truncated cone peripheral portion 4. Further, since the force is applied more toward the lower bottom of the truncated cone that opens, the cross-sectional area of the triangle is configured to increase as it approaches the opening side. It is considered that the greater the number of the second ribs 6, the higher the rigidity can be. However, in the first embodiment, sixteen second ribs 6 are provided for convenience of construction. However, it is not limited to this.

  Further, a fitting portion 7 with the can-shaped container 2 is formed on the lower bottom peripheral edge of the packaging container 1. The fitting portion 7 will be described with reference to FIG. FIG. 3 is an enlarged sectional view of the fitting portion 7 formed on the lower peripheral edge of the packaging container 1. The fitting portion 7 has a fixed groove 8 in which the packaging container 1 is inscribed in the cylindrical upper bottom of the can-shaped container 2 and a fixed interval between the fitting portion 7 in order to closely fit the packaging container 1 into the can-shaped container 2. , And a peripheral portion 10 that forms a peripheral edge of the fitting portion 7.

  The fitting groove 8 is formed so that a side edge portion provided with a certain thickness on the cylindrical bottom portion of the can-shaped container 2 is inscribed. The fitting groove 8 is formed so as to have a slight gap in the height direction of the side edge when the fitting groove 8 is mounted on the can-type container 2. A water-resistant inner lid 11, which will be described later, is inserted into the gap.

  The fitting projection 9 fits into a concave portion formed by a side edge portion provided with a certain thickness on the cylindrical upper bottom portion of the can-shaped container 2 and a peripheral edge portion of the can-shaped container 2. It is formed to protrude inside the container. As the number of the fitting protrusions 9 increases, the packaging container 1 can be more strongly fitted to the can-shaped container 2. However, if the number of the fitting protrusions 9 is too large, the packaging container 1 will not easily come off. As described above, in consideration of the operability of attaching and detaching the packaging container 1 and the adhesion to the can-shaped container 2, eight fitting protrusions 9 are provided at equal intervals in the first embodiment. When the packaging container 1 is fitted on the can-shaped container 2 and the user lifts the packaging container 1 by grasping only the packaging container 1, the two are tightly fitted, and the container 2 is lifted up in a state where the can-shaped container 2 is in contact with the packaging container 1. Further, the shape of the fitting protrusion 9 is 8 mm in width and 0.6 mm in height from the inner edge, but the present invention is not limited to these numerical values.

  The peripheral portion 10 is formed so that its diameter is slightly larger than the diameter of the fitting portion 7. This is to prevent the cut edge cut off from the sheet from becoming sharp after integrally forming the packaging container 1.

  Further, a third rib 12 is provided around each of the second ribs 6 on the peripheral portion 4 near the fitting portion 7. The third rib 12 is provided in the horizontal direction of the packaging container 1, that is, in order to oppose the force applied to the peripheral portion 4 and to increase the rigidity of the packaging container. In the first embodiment, one round is provided for the packaging container 1, but more may be provided.

  Next, the inner lid 11 will be described. As described above, the inner lid 11 is inserted into the fitting groove 8 in a slight gap with the side edge of the can-shaped container 2. The inner lid 11 has a diameter slightly larger than the diameter of the fitting groove 8 and is mounted in such a manner as to be slightly pushed into the fitting groove 8, so that the inner lid 11 is not easily detached even if the container body is inverted. . The inner lid 11 is formed of a water-resistant material, but water-resistant paper used for milk packs and the like is used in consideration of production costs and the like. In practice, it is sufficient that at least the surface of the inner lid 11 on the side of the can-shaped container 2 has water resistance.

  If the cans cooled in a refrigerator or the like are left in the air at room temperature, dew condensation may occur on the surface of the cans. Wetting can be prevented. Further, by inserting the inner lid 11 into the packaging container 1, the packaging container 1 and the can-shaped container 2 are closely fitted, so that the can-shaped container 2 equipped with the packaging container 1 is immersed in cold water. It is also possible to cool the can-shaped container 2 by pressing. Also, since the inner lid 11 has a diameter slightly larger than the diameter of the fitting groove 8 and is difficult to be detached even when inverted, the confectionery is prevented from jumping out of the bounce when the packaging container 1 is removed from the can-shaped container 2. can do.

  FIG. 4 is an overall perspective view showing a state where the inner lid 11 is locked in the fitting groove 8. The inner lid 11 is provided with a knob 13 so that the purchaser can easily remove the inner lid 11. When the inner lid 11 is formed of a material having a large elasticity, when the inner lid 11 is locked in the fitting groove 8, the inner lid 11 may be locked to the inner diameter of the packaging container 1 by the elasticity of the knob 13. It is possible.

  Next, a state in which the packaging container 1 according to the first embodiment of the present invention is actually fitted to the can-shaped container 2 will be described with reference to FIG. FIG. 5 is an enlarged cross-sectional view showing a state when the packaging container 1 according to Embodiment 1 of the present invention is fitted to the can-shaped container 2. A confectionery 14 is loaded in the packaging container 1, and the inner lid 11 is inserted between the confectionery 14 and the can-shaped container 2. The inner lid 11 and the side edge 15 provided around the can-shaped container 2 with a certain thickness are inscribed in the fitting groove 8 in the fitting portion 7. In the first embodiment, the knob 13 of the inner lid 11 is folded and inserted.

  The fitting protrusion 9 fits into a concave portion 16 formed by the side edge 15 of the can-shaped container 2 and the peripheral edge of the can-shaped container 2. In order to actually fit the packaging container 1 onto the can-shaped container 2, it is necessary to cover the packaging container 1 on the cylindrical bottom of the can-shaped container 2 and push it in by hand. At this time, since the packaging container 1 has elasticity, when the fitting projection 9 gets over the side edge portion 15 of the can-shaped container 2, it slightly spreads and converges.

  Next, a case where a purchaser or the like takes out sweets will be described. A purchaser or the like can detach the can-shaped container 2 by fixing the can-shaped container 2 by hand and pulling the packaging container 1 upward with the other hand. At this time, since the diameter of the inner lid 11 is slightly larger than the diameter of the fitting groove 8 and it is hard to come off even if it is inverted, contents such as confectionery do not fall.

  When there is excess confectionery, the purchaser or the like can pack the excess confectionery in the packaging container 1 and fit the confectionery again on the can-shaped container 2. In addition, even when soft drink or the like remains in the can-shaped container 2, the packaging container 1 can be used as a lid of the can-shaped container 2. That is, since the packaging container 1 and the can-shaped container 2 are closely fitted, even if the can-shaped container 2 is knocked down, the soft drink or the like does not spill.

  As described above, in the packaging container 1 according to the first embodiment, the fitting protrusion 9 can be fitted into the concave portion 16 formed by the side edge portion 15 and the peripheral edge portion 17 of the can-shaped container 2. It can be attached to and detached from the can with one touch. In addition, by inserting the inner lid 11 into the fitting groove 8, the contents do not fall when the packaging container 1 is removed, and the degree of sealing when fitted to the can is increased. No immersion in water drops or immersion in cold water. In addition, the packaging container 1 according to the first embodiment can be easily formed by punching a polypropylene or polyethylene sheet or the like with a mold, so that the production cost can be kept low.

  In addition, according to the present embodiment, even when dew condensation occurs on the surface of the can-shaped container when the cooled can-type container is left in the atmosphere at room temperature, water due to the dew condensation is generated inside the packaging container. Wetting of confectionery and the like can be prevented. Also, even if the can-shaped container equipped with the packaging container is immersed in cold water, since the packaging container and the can-shaped container are closely fitted and the inner lid has water repellency, the inside of the packaging container is Can be prevented from getting wet.
